Dear Eric W. Biederman.
I try to boot kernel from linuxbios. In this time, I meet serious problem. I saw your kernel startup patch for linuxbios. (x86 Boot enhancements) In my opinion, you can solve my problem.
I succeed to loading linux kernel, but Can't mount to root any device, ramdisk, hdd, nfs.
In select ramdisk as a root file system, there are different panic message by kernel module setting.
And, other device is similar to that. I think that problem is memory management, How about do you think?
If you have some idea, plz let me know.
My suggestions. 1) setup to use the external etherboot, and the linuxbios elf loader, it keeps you from being stuck with just loading Linux. 2) Load memtest86 and see if you memory appears o.k. 3) Get an oops that reports something, without running ksyms oops on the output I have no idea. Where in the kernel you are crashing.
The best clue you have given is:
VFS: Mounted root (ext3 filesystem). Freeing unused kernel memory: 244k freed attempt to access beyond end of device 03:02: rw=0, want=2147481940, limit=14651280 attempt to access beyond end of device 03:02: rw=0, want=738197788, limit=14651280
It looks like there is something fishy in your hard drive code.
I don't have any direct experience with the VIA 694X, so I don't know which kinds of things are likely to go wrong.
I am forwarding this to the LinuxBIOS list in case someone else has a clue.
Eric
Thanks for reading.
